Please ignore the latter problem. It is none, just I did not reload the object tree and reopen the object again. Maybe one might to think about a less tedious way to refresh the information in in the info tab.
The refresh button of the info tab does not work.
DbVisualizer 13.0.1 has just been released with a fix for this problem.
Easiest is that you open Help->Check for Update in DbVisualizer to perform the upgrade. An alternative is that you download from our website: https://www.dbvis.com/download/
I will open a ticket and we'll have a look.
